このシステムについて実証された利点は、使用者が上記
操作レバーに加えた力が大幅に増倍されることであり、
通常は非常な力を必要とする非常に細い針による液体の
注射や、粘性がきわめｔ高いペースト等の押し出しが容
易になる。A demonstrated advantage of this system is that the force exerted by the user on the operating lever is significantly multiplied;
This makes it easier to inject liquids with very thin needles, which normally require a great deal of force, and to extrude extremely viscous pastes.
ただし、上記ピストンから注入物にかかる圧力が過大に
なると、上記システムの構成要素のいずれかの強度を上
回り、このため液体を入れたカルビュール（ｃａｒｐｕ
ｌｅ ）が毀れたり、上記操作レバーの回転軸がずれる
恐れがある。However, if the pressure exerted by the piston on the injectate becomes too great, it may exceed the strength of any of the system components, thus causing the liquid-filled carbule to become too strong.
(le) may be damaged or the rotation axis of the operating lever may be displaced.
本追加証明書は、押出し物にかかる圧力を制限する装置

本発明の作動と利点は別添の図と下記の説明により明ら
かにされる。The operation and advantages of the invention will be apparent from the accompanying drawings and the following description.
第１図および第２図において、１は注射器本体の前部で
あり、主特許（Ｎｏ、８２．１８５４６ ）およびその
最初の３部の追加証明書（Ｎｏ、８３．１２９３２，８
３．２０５２８．８４．１７２２６ ）の場合と同様に
、その先端に針ガイドを備えている。In Figures 1 and 2, 1 is the front part of the syringe body, which includes the main patent (No. 82.18546) and its first three additional certificates (No. 83.12932, 8
3.20528.84.17226), it is equipped with a needle guide at its tip.
本発明によれば、上記注射器本体の後半部は、さらに中
間部３と後部４の２つに分かれている。According to the invention, the rear half of the syringe body is further divided into two parts: a middle part 3 and a rear part 4.
中間部３は、通常の方法に従いソケット５により上記前
部１に差し込まれている。The intermediate part 3 is inserted into the front part 1 by means of a socket 5 in the usual manner.
後部４は、ネジ部６によって上記中間部３と結合されて
いるが、ネジを切った理由は後で詳しく説明する。The rear part 4 is connected to the intermediate part 3 by a threaded part 6, and the reason for cutting the thread will be explained in detail later.
注入物Ｇ；正圧力かける装置は、上記主特許および以前

て動く第１ラチエツト８と、押しボタン１１によって引
き外すとラック７を後退させることのできる第２ラチエ
ツト１０とが噛み合っている。Injection G: The device for applying positive pressure is a piston, as in the above-mentioned main patent and the previous supplementary certificate, and teeth attached to a rack 7 on the upper surface of the piston have a first ratchet 8 and a ratchet 8 moved by an operating lever 9. , and a second ratchet 10 which, when pulled out by a push button 11, allows the rack 7 to be retracted.
発明によれば上記操作レバー９の回転軸１２は、注射器
本体の固定部にではなくフェザ−キー１３に取付けられ
ており、該フェザ−キー１３は上記中間部３の直径上に
正対する２本の母線に沿って切った案内溝（案内部）１
４の中を注射器本体の長手方向に沿って摺動する。According to the invention, the rotating shaft 12 of the operating lever 9 is attached to a feather key 13 rather than to a fixed part of the syringe body, and the feather key 13 has two feather keys 13 directly facing each other on the diameter of the intermediate part 3. Guide groove (guide section) 1 cut along the generatrix of
4 along the longitudinal direction of the syringe body.
上記フェーザーキ−１３は圧力補償装置に支えられてい
る。該圧力補償装置は、上記注射器本体の中間部３の肩
部１７に位置する押えワッシャ１６と上記注射器の後部
４の反対方向を向いたもう一つの肩部１８との間に配置
されたバネ１５により構成されている。The phaser key 13 is supported by a pressure compensator. The pressure compensator comprises a spring 15 arranged between a hold-down washer 16 located on a shoulder 17 of the middle part 3 of the syringe body and another shoulder 18 facing in the opposite direction of the rear part 4 of the syringe. It is made up of.
上記中間部３は、後部４のネジ部６と組み合わされたネ
ジ山を有するロッド１９によってこの後部４の中まで続
いている。The intermediate part 3 continues into this rear part 4 by a threaded rod 19 which is combined with the threaded part 6 of the rear part 4 .
該後部４の中間部３に対するネジ込みを加減することに
より、上記バネ１５の圧縮状態を調節して、抵抗力を調
節することができる。By adjusting the screwing of the rear portion 4 into the intermediate portion 3, the compression state of the spring 15 can be adjusted and the resistance force can be adjusted.
操作に際しては、医師が操作レバー９を矢印Ｆの方向に
押すと、第１ラチエツト８がラック７の歯と噛み合って
このラック７を前進させ、上記操作レバー９を押す度に
ピストン・ヘッド２０が歯の長さ分ずつ前進する。In operation, when the doctor pushes the operating lever 9 in the direction of arrow F, the first ratchet 8 engages with the teeth of the rack 7 to advance the rack 7, and each time the operating lever 9 is pushed, the piston head 20 moves forward. Move forward by the length of the tooth.
したがって、医師は注射器本体の先端部（針ホルダ）２
から上記前部１に含まれた物質を一定量押し出すことが
できる。Therefore, the doctor should
A certain amount of the substance contained in the front part 1 can be extruded from the front part 1.
これを明らかに示すために、液体を入れたカルビュール
と、針ホルダ２に針がない状態の前部１を図示した。ま
た、この前部１は上記針ホルダ２に入れたカニユーレか
ら押し出すペーストを入れる場合は構造を変えることが
できる。In order to clearly show this, the front part 1 is shown with the carbule filled with liquid and without the needle in the needle holder 2. Moreover, the structure of this front part 1 can be changed if a paste is to be extruded from the cannula placed in the needle holder 2.
いずれの場合にも医師は同じような問題にぶつかってい
る。すなわち、上記操作レバー９を何回か操作した後に
上記ピストン・ヘッド２０が最大限に圧縮されるので、
液体封入カルピュールのゴム栓またはペースト状物質に
増々大きな抵抗がかかることとなる。力Ｆは非常に減速
されるので、操作レバー９の連続操作は可能であるが、
一方で液体封入力ルピュールまたは注射器の機械的要素
の抵抗、特に操作レバー９の回転軸１２の抵抗が応力よ
り小さくなる。そのため、上記カルピュールが破裂した
り、上記回転軸１２を初めとする機械的要素の一つが破
損することがある。In both cases, doctors face similar problems. That is, after the operation lever 9 is operated several times, the piston head 20 is compressed to the maximum.
The rubber stopper or pasty substance of the liquid-filled Calpur is subject to increasing resistance. Since the force F is greatly reduced, continuous operation of the operating lever 9 is possible, but
On the other hand, the resistance of the mechanical elements of the liquid sealing force Lupure or the syringe, in particular the resistance of the rotation axis 12 of the operating lever 9, becomes smaller than the stress. Therefore, the Calpur may burst or one of the mechanical elements including the rotating shaft 12 may be damaged.
この問題を解消するため、バネ１５をこの許容最大応力
に等しい値に較正したので、操作レバー９を操作し続け

はフェザ−キー１３と共に後退して、上記ラック７の噛
み合っていた歯が外れる。内容物および注射器の機械的
要素にかかる応力はあらゆる破断を防止するためこの許
容最大値に限定され、この応力の移動は較正バネ１５に
よって受は止められる。In order to solve this problem, the spring 15 was calibrated to a value equal to this maximum allowable stress, so that if the operating lever 9 is continued to be operated, the spring 15 will be compressed, which will cause the rotating shaft 12 to
moves backward together with the feather key 13, and the engaged teeth of the rack 7 are disengaged. The stress on the contents and the mechanical elements of the syringe is limited to this maximum permissible value to prevent any breakage, and the transfer of this stress is counteracted by the calibration spring 15.
したがって、不注意な操作の場合にも一切の注射器の破
損の恐れが避けられる。Any risk of breakage of the syringe in case of careless operation is thus avoided.
この圧力補償装置の別の作用として、操作レバー９を急
速に操作すると、ピストン・ヘッド２０が大きな圧力を
かける前に上記バネ１５は瞬間的に圧縮され、その後部
々に該バネ１５がピストンを押すので、上記ピストン・
ヘッド２０はゆっくり徐々に注入物を押し出すこととな
り、カルビュールや注射器の機械的要素の破損の恐れは
なくなる。Another effect of this pressure compensator is that when the operating lever 9 is actuated rapidly, the spring 15 is momentarily compressed before the piston head 20 exerts a large pressure, and the spring 15 presses the piston at its rear. Because it pushes, the above piston
The head 20 will force out the injectate slowly and gradually, eliminating the risk of damage to the carbule or mechanical components of the syringe.
このバネ１５の較正により、この応力制限器を、押し出
す物質の性質、すなわち針の細さまたは押し出すペース
トの粘性に合わせることができる。This calibration of the spring 15 allows the stress limiter to be matched to the nature of the material to be extruded, ie the fineness of the needle or the viscosity of the paste to be extruded.
上記圧力補償装置のもっと大まかな別室では、上記バネ
１５をラック７と操作レバー９を支点とする単純な板バ

ラック７の歯の非常に強い抵抗に出会うと、この板バネ
がたわんで上記操作レバー９の応力がラック７に、次い
でピストン・ヘッド２０に伝わらないようにする。In a more general separate chamber of the pressure compensator, the spring 15 can be replaced by a simple leaf spring whose fulcrums are the rack 7 and the operating lever 9. Therefore, when the ratchet 8 encounters a very strong resistance of the teeth of the rack 7, this leaf spring deflects and prevents the stress of said operating lever 9 from being transmitted to the rack 7 and then to the piston head 20.
補足説明として、このピストン・ヘッド２０は、２つの
